[. . . ] The slot board carries the PCI and ISA bus slots for system enhancements and future expansion. The slot board may vary in size and layout depending on your system housing. Figures 1-2 and 1-3 show the two kinds of slot boards.

The system board comes with a 1-MB video memory onboard upgradable to 2 MB. Locate the video DRAM upgrade sockets labeled U39 and U40 on the system board. The WaveTable does not come with the basic system. The WaveTable daughterboard supports the same external connectors as the audio-I/O board but comes with enhanced audio features. It bundles the Crystal chipsets that work together to produce better sound quality. Figure 1-12 shows the WaveTable daughterboard layout. Microphone Port Line-in Port Line-out Port MIDI/Game Port Figure 1-12 WaveTable Daughterboard 1-22 User's Guide The WaveTable has two connectors, CN5 and CN6, located underside. Match these two connectors with the audio-I/O connector (CN9) and WaveTable connector (CN6) on the system board. Figure 1-13 shows how to install the WaveTable connector.

QuickStart turns off the hard disk, monitor, keyboard, and mouse once you press the power switch for less than four seconds while the system is on. This feature requires the Power Saving Operation Mode parameter in the BIOS to be set to QuickStart. See section 2. 4 for more information on the setting description. The system board comes with connectors to support the QuickStart feature. The following sections tell how to connect the power switch and LED cables, and enter QuickStart mode. 1. 10. 1 Connecting the Power Switch and LED Cables The Aspire housing comes with a special power and LED cables to connect to the LED board. Connect the 6-pin power switch connector to JP50 on the LED board, matching the white cable with pin 1. Connect the 3-pin HDD/MSG LED to pins 1-3-5 of JP48, matching the green cable with pin 1. Connect the 3-pin power switch LED cable to pins 2-4-6 of JP48 making sure that the green cable matches pin 2. See Figure 1-15. System Board 1-25 Power HDD/MSG Figure 1-15 Power and HDD/MSG Connector (JP48) Figure 1-16 shows the locations of JP48 and JP50 on the system board and which cables to connect to them.

This action causes the system to rest (QuickStart state 1) by turning off the keyboard, mouse, and monitor. After the specified time in the QuickStart State Timer parameter in BIOS, the system sleeps (QuickStart state 2) and turns off the hard disk. Once the system enters QuickStart mode, the hard disk/message LED and keyboard LED go off, while the power and monitor LEDs start blinking. [. . . ] An equipment malfunction is more likely to cause a fatal error, i. e. , an error that causes complete system failure. You must know the correct configuration values for your system before you enter Setup, which is why you should write them down when the system is correctly configured. An incorrect configuration is a major cause of power-on error messages, especially for a new system. [. . . ]
